Title: Warning device for the malfunctioning of a flash output control system in the case of an automatically controlled flash output light brightness
Inventor: HASEGAWA HIROSHI
IPC: H05B41/32
Filed: 1981-01-28
Abstract: A warning device of the malfunctioning of a flash output control system when photographing by means of a camera is provided which has a circuit for determining the quantity of light which is designed such that it starts to operate in time with the shutter release and is transferred from a first state into a second state when an integrated quantity of light coming from a subject to be taken reaches a predetermined value. Furthermore, the warning device comprises a time counting circuit which counts a predetermined time T2 which is longer than the longest light emission time for a flash light discharge tube in time with the shutter release. The device also comprises a memory circuit which is designed such that it starts to store the state of the circuit for determining the quantity of light after the light emission time of the flash light discharge tube has expired and before the predetermined time T2 has expired. This memory circuit stores up to an instant T3. The warning device further comprises a discrimination circuit by means of which the state of the circuit for determining the quantity of light, which circuit is stored by means of the memory circuit, is determined at an instant at which the time counting circuit has counted the predetermined time duration T2. If, in the process, the first state has been determined, the malfunction signal is output and a warning device is actuated which is controlled by the malfunction signal of the discrimination circuit. <IMAGE>

Patent DE-3108767-A1 (DE)
Title: Medical blood pressure sensor
IPC: G01L9/00
Filed: 1981-03-07
Abstract: A pressure sensor for invasive blood pressure measurement has a membrane which is exposed to the blood pressure and by the deflection of which a light path is shadowed. Evaluation of the light passing through permits determination of the blood pressure. Shadowing can be achieved, for example, by displacement of a diaphragm in the light path or by deflection of the light path emitter or receiver by means of the membrane, preferably by deflection of a flexible light guide. The latter embodiment, in particular, can be miniaturised down to a diameter of the blood pressure sensor in the range of 0.5 mm, and it is very suitable for catheter applications. Miniaturisation permits provision of further probes, for example for oxygen determination in the immediate vicinity of the pressure sensor, preferably as a carrier of conductive layers, which are used, for example, for polarographic pO2 determination, on use of the light guide. <IMAGE>

Title: Solar power station with photovoltaic cells
Inventor: BOESE KARL-FRIEDRICH DIPL PHYS
IPC: H02S40/22
Filed: 1981-03-11
Abstract: A solar power station, in particular of a relatively small size, for generating both electricity and useful heat. Photovoltaic cells (34) are fitted to a hollow holder (33) bearing a flow of cooling fluid. That part of the light spectrum which can be converted into electricity by the photovoltaic cells only at a low efficiency or not at all is filtered out by tubular glass bodies (31, 32), so that the heat loading on the photovoltaic cells is reduced. In the annular space between the glass tubes (31), the cooling fluid preheated in the interior of the holder (33) circulates and is further heated here by its own heat absorption and the removal of the heat absorbed in the glass bodies (31, 32). This cooling fluid can be used for heating purposes. The glass bodies (31 and 32) can be made of glasses of different types, which absorb light in the lower or upper part of the spectrum respectively. <IMAGE>

Title: Track for high-performance magnetic levitation railways
Inventor: WAGNER PETER DR ING
IPC: E01B25/32
Filed: 1981-03-23
Abstract: The invention relates to tracks for magnetic levitation railway systems in which the carrying and guiding of the vehicles takes place in a contactless fashion according to the electromagnetic, electrodynamic or permanent magnetic principle and the vehicles are also driven in a contactless fashion by the use of linear motors. The track for such magnetic levitation railway systems consists generally of the vehicle carriers and the pillars supporting them. The track carrier itself is equipped with a series of functional components for realising the carrying, the guiding and the driving of the vehicles. In addition, the track contains independent components for setting down the vehicle in the event of power failures. The invention has the object of designing the connection of the functional components in such a way that on the one hand a full power flux between track carrier and functional components is achieved and, secondly, each functional component can be individually adjusted and, if appropriate, replaced. The second property is achieved in particular by the fact that the connection structures are each realised in dual construction methods.
Patent DE-3115203-A1 (DE)
Title: Turbine-driven rotor
Inventor: STURM MICHAEL
IPC: F02B41/10
Filed: 1981-04-15
Abstract: Turbine-driven rotor for use in motor vehicle engineering. Problem: petrol economy, improved acceleration, attainment of a higher output speed. The problem is solved by a rotor inside a fuse box, outside the body, which is in turn made to move by an exhaust gas-driven turbine. The dynamic pressure of the high-energy gases can be controlled by means of a bypass valve. In this way the dynamic pressure in the manifold can be varied. If the pressure increases, for example, due to corresponding spring tensioning of the bypass valve, the gases escape at a higher velocity along the turbine blades, thereby assisting the turbine to reach a higher number of revolutions, which in turn allows the rotor to run faster. With a certain forwards inclination the rotor has a spoiler-like effect, which occurs significantly earlier than with conventional spoilers. In this way the contact pressure and hence the road contact is discernibly improved right from the beginning. Principal potential application: motor vehicle construction, or vehicles producing exhaust gas. <IMAGE>

Title: Electrical resistor having at least one resistance film, which is applied on a carrier, and a method for producing an electrical resistor
Inventor: GRUNER HEIKO DIPL PHYS DR
IPC: H01C1/034
Filed: 1981-04-18
Abstract: An electrical resistor is proposed having at least one resistance film, which is applied on a carrier, and a method for producing an electrical resistor. The electrical resistor (20) consists of a carrier (17) on which a resistor film (3) is applied, a resistor film (4) being applied on the other side, whose length (a') and width (b') are shorter than the length (a) and width (b) of the carrier (17), and a protective film (18) which is applied onto the resistance film (3, 4). The electrical connection (22) between the protective films (3, 4) can be made via a hole (21) in the carrier (17). In accordance with the method according to the invention, a solid resistance film is applied onto a base plate, which resistance film is split into individual resistance films, by means of an etching process, with separating joints being formed. After this, a laser beam is used to score along the course of the separating joints, and a protective film is subsequently applied onto the resistance film and the separating joints. The base plate is now broken along the scores in order to form the individual resistors. In consequence, automated, cost-effective and precise production of electrical resistors is possible. <IMAGE>

Title: Manual starting crank device for internal combustion engines
Inventor: EIBL HEINZ DIPL ING
IPC: F02N1/02
Filed: 1981-07-29
Abstract: The invention relates to a starting crank device for internal combustion engines with a hand crank and a starting crank journal which can be connected to the element of the internal combustion engine to be turned by way of a carrier coupling which can be released in the direction of the crank axis, a freewheel device equipped with two bearing elements and interposed clamp elements being provided, which permits movement of the starting crank journal in the axial direction but in the opposite direction prevents any movement after a short idle movement. The object of the invention is to create a starting crank device which on the one hand is cheap to manufacture and on the other reliably protects the operator against kickback of the hand crank during operation. This object is met in that the one bearing element of the freewheel is firmly seated on the starting crank journal whilst the other bearing element is firmly connected to a disengager which in the event of movement in the starting direction bears against a stop surface fixed to the housing but in the event of movement in the opposite direction acts in concert with a control surface fixed to the housing and inclined in relation to the crank axis in such a way that the disengager together with the starting crank journal and hand crank are axially adjusted and the carrier coupling is released. The device is shown in Fig.1 in the enclosed drawing of the application. <IMAGE>

Title: Method and apparatus for determining the quantity of molten metal in a treatment or transfer vessel
Inventor: SINDELAR GUENTER DR ING
IPC: B22D2/00
Filed: 1981-11-14
Abstract: Particularly when alloying molten metals in a melting furnace, it is necessary to determine the quantity of molten metal in order from this to determine the required quantities of alloy components using the results of an analysis. In order to be able to work towards precisely predetermined alloy limits more rapidly by more accurate determination of the quantity of molten metal, the geometry of the reception chamber of the vessel is precisely determined before the material to be treated is introduced and the exact level of molten metal relative to a reference point is then determined at the point in time at which the quantity of molten metal is to be determined and, from the level of molten metal and the previously determined geometry of the reception chamber, the exact volume of molten metal is finally calculated.
